In the drawings illustrating certain embod- Vents of the invention Fig.l is a front elevation of one end of a yarn Carrier or tube frame Withsupported yarn spool;

Fig. 2 is a. vertical section transversely through the carrier and spoolof Fig. l, showing also a port-ion of a yarn engaging instrumentality ofthe loom in position about to Fig. 3 is a bottom plan of the carrier asin Fig. l;

Figs. et and 5 are respectively perspectives of a single yarn-spacingand gripper-guiding member such as 'llustrated in Figs. 1 to 3, and

a section of an attaching` element or strip therefor; and

Figs. 6 and 7 are respectively a vertical cross-section through amodified form of cariier, and a. plan of a portion thereof.

Referring more particularly to the drawings and first to Figs. l to 5,the tuft yarn carrier or tube frame as illustrated` comprises a frame lor main longitudinal sup- 5 porting element, shown as a tubular metallicmember but which may be of other material or otherwise formed, forinstance, as a Wooden bar. Said frame or carrier proper is of a lengthto support along it one or more tuft yarn spools, as required, a portionof one spool being shown at 2. The spool is rotatably supported upon theframe as by means of the bearing member 3 receiving the spool pintle e,similar means being provided at the opposite end of the frame, and at anintermediate point or points Where a plurality of spools are to besupported. The frame is adapted for connection with the carrier chain othe loom in any desired or usual manner as i by means of the chainengaging member 5 and the hook-latch G provided at each end of thecarrier frame.

The series of yarns or yarn units 7 extend from the spool 2 upon whichthey are Wound across one face of the frame l, that at the left asviewed in Fig. 2. For convenience in description this side or face ofthe frame, across which the yarn ends extend, Will be referred to as theframe front, While the face or portion of the frame at an angle theretoand below it Will be referred to as the under portion or bottoni of theframe.

Along one face of the frame, the bottom face as herein illustrated, isprovided yarn spacing and gripper guiding means herein comprising alongitudinal series of guide members, guides or barriers 9 illustratedas metallic strip-like devices or bars distributed along the frame inedgewise relation to it and each with one end extending outwardly beyondthe bottom face of the frame, at the side across which the yarns 7extend.

Suitable means is provided for attaching said yarn-s acing andgripper-guiding means to the frame l. Herein for the purpose there isillustrated a longitudinal element or attaehing strip l0t best seen inFig'. 5, having at suitable intervals apertures ll for receiving aAfastener such as the screw or bolt l2, Fig. 2, extending throughcorresponding openings in the adjacent face, herein the bottom face, ofthe frame 1 and removably engaging the opposite frame Wall as by meansof the locknnt 13. rllhe edge of the fastener-receiving apertures ll ofthe attaching strip may be 11p-set as indicated at le, Figs. 2 and 5 toinsure accurate positioning` of the attaching strip upon the frame.

Said attaching strip as illustrated is formed with a depending flange 15which, together with. the adjacent. portion of the strip, if desired,has a series of formations such as slots, notches, perforations or thelike 16. each adapted to receive one end, herein the inner end, of oneelement or member 9 of the spacing and guiding means. The inner ends ofsaid members or guides 9 are. adapted to be received in said formations1G, pref-erably with a slightly loose lit, and as shown are formed eachwith a tongue l? for reception in llt) the corresponding formation 16 ofthe attaching strip 10.

Along a portion of the attaching strip spaced from the flange 15additional means for positioning and holding the yarn-spacing andgripper-guiding members or guides preferably is provided. Said means asherein illustrated is of relatively small height as compared with theflange 15, being in the form of a hollow or approximately U-shaped rib18 bent or struck up from the body of the strip lO and preferablyrounded substantially as illustrated. Said rib 18 is formed with aseries of slots, notches or the like 19 registering with the formations16 of the strip flange and of a width to receive each a guide 9, alsoireferably with a slightly loose lit, said rib thus comprising in effecta series of spaced straps or eyes aligned lengthwise of the strip.

The guides 9 are assembled with the attaching strip 10 so that anintermediate portion of each guide lies in a slot or recess 19 of therib 18 and an end portion, herein the inner one, is received in thecorresponding slot,

' notch or other formation 16 of the flange 15.

To hold or lock said guides in assembled position suitable means isprovided, such as the locking pin or bar 20 adapted to be passed throughand beneath the rib 18 and through a locking formation or aperture 21provided for the purpose in each guide.

At the outwardly extending ends of the guides 9 means is providedwhereby the respective yarn units will be retained in properly spacedfeeding position, one between each two adjacent guides, said means beingarranged to permit broadside threading or positioning of the yarns insaid relation, when desired. In the present embodiment of the inventioneach guide 9, as best seen in Figs. 1, 3 and 1, accordingly has formedat or near its outer end portion a locking device or laterally deflectedbarb-like nib 22 having an inwardly inclined forward or outer edge, asindicated at 23. The nib 22 of each guide 9 projects above and to oracross that of the next adjacent guide, but spaced suiiiciently from itto permit a yarn unit to be entered past the nib in a broadwise manner,being guided into position by the nib and the adj acent guides. Afterbeing entered beyond the nib, a yarn unit is located and retainedpositively against reverse escape in the yarn passage 2-l, seeparticularly Figs. 3 and f1, between the inner edge of the nib and thecarrier frame.

Said passages 24, as herein illustrated, are further defined by means ofadditional offsets or shoulders 25 formed on the guides 9 andcooperating with the nibs 22 and with the adjacent portions of theguides 9 to provide a substantially completely surrounding wall for eachyarn passage 24, see particularly Fig. 3, in which its yarn unit will bepositively retained yet into which the yarn may be entered in abroadside fashion. Accidental lengthwise withdrawal or slipping back ofthe yarn may be retarded or prevented by forming either the nibs 22 orshoulders 25 or both, as shown, at their opposite under edges withdepending and slightly converging burrs, lips or the lilre as indicatedat 26 upon the nibs and at 27 upon the shoulders. While the yarns mayfeed freely downward between said formations 26 and 27, the latter willengage thc yarn libres and prevent upward retraction of the yarns.

lt will be understood that in the weaving operation an instrumentalityof the loom, such as the nipper or grippers G shown in part in Fig. 2,is entered into and guided in each inter-guide space to engage or .graspthe yarn therein, to draw it into the warp. By giving the guides 9 asomewhat loose lit in their' supporting means, herein the strip l() aspreviously described, the resulting slight play affords a certainflexibility in the cooperation of the grippers with the guides, allowingthe latter to adjust themselves to the noses of the grippers in case anyof thc latter should tend to catch or bind while being inserted orwithdrawn. The .shoulders 25 on the guides are also useful in thisconnection, acting as stops or guides for the inner ends of the grippersand further insuring their proper engagement with the adjacent yarns, asdoes also the adjacent rounded portion of the rib 18 of the attachingstrip.

It will be further noted that the yarns may feed freely down through andbetween the several guides 9, the space between the latter beingentirely free and unobstructed by the attaching strip or otherwisesubstantially from the outer ends of the guides to their opposite ends,and below the yarn retaining nibs 22 and shoulders of the guides 25 andthe shallow rib 18 of the attaching strip 10. Also the guides 9preferably are markedly recessed or cut away at one or both long edges,as illustrated at 28 in Figs. 2 and 4.

In Figs. 6 and 7, in which parts not otherwise mentioned may be similaras in precec ing figures, the vertical yarn passages and the means forretaining the yarns therein while permitting their broadsidc receptionare formed integrally with the barriers or guides 9 as in the form ofFigs. l to 5. In this inst-ance the upper forward portion of each ofsaid guides 9 is recessed or stamped out, substantially as illustrated,to form a reversely extending finger or nib which is also laterallydeflected, in a sinuous manner, as clearly seen in Fig. 7. The inner endof each of the lingers 35 extends across to and above the recess in theadjacent guide 9 thus barring a yarn positioned in the passage 36against escape outwardly unless intentionally bent out around the innerend of the finger.' ln the opposite or threading direction, however, theyarns may readily be entered into the respective passages 36 broadwise.
